Romans 4:6

4:6 So even David himself speaks regarding the blessedness of the man to whom God credits righteousness apart from works:

Romans 11:33

11:33 Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how fathomless his ways!

Romans 14:21

14:21 It is good not to eat meat or drink wine or to do anything that causes your brother to stumble. ¹ 

¹ tc A large number of mss, some of them quite important (Ì^46vid א² B D F G Ψ 0209 33 1881 Ï lat sa), read “or to be offended or to be made weak” after “to stumble.” The shorter reading “to stumble” is found only in Alexandrian mss (א* A C 048 81 945 1506 1739 pc bo). Although external evidence favors inclusion, internal evidence points to a scribal expansion, perhaps reminiscent of 1 Cor 8:11-13. The shorter reading is therefore preferred.
